Clear all captured network data without stopping the capture session. Resets request/response buffers while keeping capture active. Useful for long-running captures where you want to periodically clear old data to prevent memory issues.
AI agents call clear_network_capture to permanently remove resources in WebScout MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool irreversibly discards all captured network traffic data by resetting the request/response buffers. Once cleared, the previously captured data cannot be recovered. While the blast radius is limited to in-memory captured data (not persistent storage or external systems), the action is explicitly irreversible, placing it in the Destructive category.

Clear all captured network data without stopping the capture session. Resets request/response buffers while keeping capture active. Useful for long-running captures where you want to periodically clear old data to prevent memory issues. It is categorised as a Destructive tool in the WebScout MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the WebScout MCP server in PolicyLayer and add a rule for clear_network_capture: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches WebScout MCP. Nothing to install.
clear_network_capture is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the clear_network_capture rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for clear_network_capture. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
clear_network_capture is provided by the WebScout MCP server (pyscout/webscout-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
